Stromatolites

After the boat trip we had another look at the dolphins (one caught a fish right in front of us whichh was cool!) and then got back on the bus...
We drove north some more and stopped at the Stromatolites. The Stromatolites are the oldest living organisms on earth and are where scientist believe all life started from!
They are bacteria which form into what look like rocks. Pretty cool to see as it is where life started, they are around 3.5 billion years old too!
